This Tantra should not be used on anyone without any grave problem or trouble. If there is a threat to life then only one should use this tantra. This experiment should be done to secure self or else it will prove to be harmful. People with arrogance and those who want to establish their control on others and people who are not mentally stable should not do this experiment or else it will prove to be disastrous. http://www.hanumanjyotish.com/....puja/shatru-maran-pr
